Could be that your idle speed is too low; are you idling at least at 1100rpm? Easy to adjust; I had the same when I first got the bike, you can adjust the idle/air screw easily and that could fix your issue right there.

Here is a link to where the adjustment screw is located on yours; it should be on the right side just below the tank.

2 classic signs that the timing chain is 1 tooth off on the crankshaft sprocket. We've seen this dozens of times.

Surely it would run like a bag of rusty old bolts but it runs as smooth as any thing and the cutting out would be there all the time not intermittently thanks for the advice though

Throttle body sync on a Gen1/2 can limit the upper end of idle speed adjustment... Reference screw #3 must be out 3/4 of a turn, maybe 7/8, then all others sync to it.

You didn't mention mileage, but also check the vacuum line to the MAP sensor is not blocked with waxy build-up at the vac nipple or the hose itself full length.

My mileage is 49000 thanks for the advice I have got 3 months warranty with the bike and the dealer seems to think it is caused by clutch dragging not sure if he is correct but he has said he is going to change the slave cylinder and see if that does the trick any thoughts on what he has said thanks

If the cause is clutch dragging, likely slave is not bad, but check the lever pivot and the brass bushing that pushes the plunger..... many are worn and scored and can cause clutch/shifting issues.
You would greatly benefit by flush and bleeding that clutch fluid every year... if it hasn't been done, then it will be very dark and you won't like the colour in the reservoir.
If you're getting a free slave cylinder, take it, why not.
